Syntax for Entering Functions in Interactivate Activities

Numerical values entered should be accurately calculated from 10
-8 to 10
8. Numbers larger or smaller than these values produce unreliable results. You may use
scientific notation for entering functions in the form: mantissa followed by an e followed
by 10 raised to the desired power. For example 0.000032 would be input as 3.2e10^-5.

* When x is less than zero, the exponent must be written as a whole number or in fraction
form, not a decimal. For instance, if you want to graph the fifth root of negative numbers,
you must write x^(1/5),
notx^(0.2).
